BASIONYM: Nitzschia paleacea Grunow in Van Heurck 1881
LM scalebar = 10 µm = 80 pixels.
Observations
Contributor: Pat Kociolek - September 2011
Length Range: 15.0-50.0 µm
Width Range: 1.5-4.0 µm
Striae in 10 µm:
Description
The valves are narrowly linear-lanceolate and taper gradually to very narrow, rounded ends. The fibulae are evident but short, with a density of 14-18 in 10 µm. A distinct central nodule is present. The striae are not visible in the light microscope.

- Valves narrowly linear-lanceolate
- Striae not visible in LM
- Central nodule present
- Apices gradually tapered
Valves are very slender with gradually tapered apices. The striae are very fine and not visible in the LM. A central nodule is present.
Compare
Nitzschia paleacea is more slender and has more gradually tapered apices than N. palea, N. palea var. debilis, and N. palea var. tenuirostris. Nitzschia paleacea is further distinguished from these taxa by the presence of a central nodule.
